1 XC654 Series ETR47-7.6μA Ultra Low Power Consumption Small Voltage Regulator (CL Capacitor-Less) GENERAL DESCRIPTION The XC654 series is a highly accurate CMOS voltage regulator that achieves very low supply current operation of.6μa. Even output current is μa (when light load), the XC654 can provide high accurate outputs, which is ideally suited for the applications to draw less output current. The usage of super small package USPN-4B (.75 x.95mm) and the advantage of capacitor-less stable operation can contribute the board space saving outstandingly. The IC consists of a reference voltage source, an error amplifier, a driver transistor, over-current protection circuit, and a phase compensation circuit. The device is compatible with a low ESR ceramic output capacitor CL. Moreover, the device can provide stable output even without a CL output capacitor because of the excellent internal phase compensation. Output voltage is fixed internally by laser trimming technology and can be selectable in.v increments within the range of.v to 5.V. The CE function enables the device to be put into standby mode by inputting a low level signal to the CE pin thereby reducing current consumption to less than.μa. In the standby mode, if a CL output capacitor is used, the electric charge stored at CL can be discharged via the internal switch and as a result, the VOUT pin quickly returns to the VSS level.

8 XC654 Series OPERATIONAL EXPLANATION The voltage divided by resistors R & R is compared with the internal reference voltage by the error amplifier. The VOUT pin is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled and stabilized by a system of negative feedback. XC654 Series, Type A <Current Limiter, Short-Circuit Protection> The XC654 series includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the operations of the current limiter and circuit protection. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, output voltage drops further and output current decreases. <CE Pin> The XC654 internal circuitry can be shutdown via the signal from the CE pin with the XC654 series. In shutdown mode with CE low level voltage is input, output at the VOUT pin will be pulled down to the VSS level via parallel to R & R and CL discharge resistance (RDCHG). If this IC is used with the correct output voltage for the CE pin, the logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry when medium voltage is input. The output voltage becomes unstable when the CE pin is opened. <CL Auto-Discharge Function> The XC654 series can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the CE pin, which enables a whole IC circuit put into OFF state, is inputted via an internal switch located between the VOUT pin and the VSS pin. In this state, the application is protected from a glitch operation caused by the electric charge at the output capacitor (CL). Moreover, discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (RDCHG) and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value (RDCHG) and an output capacitor value (CL) as τ(τ= CL x RDCHG), the output voltage after discharge via the internal switch is calculated by the following formulas. Please also note RDCHG is depended on VIN and When VIN is high, RDCHG is low. V = VOUT(E) e -t/τ or t=τln(vout(e) / V) V: Output voltage after discharge VOUT(E): Output voltage t: Discharge time τ: CL x RDCHG <Low ESR Capacitors> The XC654 series can provide a stable output voltage even if without CL capacitor or with a low ESR CL capacitor because of a built-in phase compensation circuit. In case of adding a CL capacitor, we suggest that an output capacitor (CL) is connected as close as possible to the VOUT pin and the VSS pin. When VIN stabilization is needed, please place an input capacitor (CIN) as close as to the VIN pin and the VSS pin. 8/

9 XC654 Series NOTES ON USE. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded.. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please keep the resistance low between VIN and VSS wiring in particular.. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible. 4. Capacitances of these capacitors (CIN, CL) are decreased by the influences of bias voltage and ambient temperature. Care shall be taken for capacitor selection to ensure stability of phase compensation from the point of ESR influence. 5. Torex places an importance on improving our products and their reliability. We request that users incorporate fail-safe designs and post-aging prevention treatment when using Torex products in their systems. 9/
